To all whom it may concern:

lie it known that l, JonN ALBERT Os'rnN- mans, a citizen of the United States, res ding-at lampbell, R. R. No. 9, in the county of Santa Clara and State of California, have invented a new and useful Improvement in e Magneto Drive for Internal- Combustion Engines, of which the follow ing as a specification.

My invention relates to an improvement in a, magneto drive for internal combustion engines; and the particular improvements ther in consist of certain novel ports and colonisation of parts. the separate features of which will be specifically pointed out in the claims concluding this specificctiozn'in connection with the drawings illustrating seine.

object of my invention is to cause the ten 9 to tire the initial charge in starting o'hen the engine is turned over slowly by hand or otl'ierwise and also to automatically 'the timing u-von. accident from back-tiring.

Mv invention will be described in detail iter and illustrated in the accom- .nving drawings, in which Figure 1 is a ertical section magneto drive. Fig. is a on line AA of ig. Fig. 3 1s sectionsl view through gear 5 showing the operating" spring attached to the gear and collar. Fig. i: is a side elevation of my o.) invention "when the. cam shaft is connected direct to the magneto shaft. F ig. 5 is a cross section on line BB of Fig. 4-. Fig. 6 s. cross section on line C -C of Fig. 4.

' rring now more particularly to the the-Wings, Wh reinlike reference charscters indicate corresponding parts in all the views-1 indicates the camshaft of an internal combustion engine, from which is driven cam shaft 2 which is turncole and slideble in bearing 3, said bearing being attached to irsrne 1*. {in the outer end of coin shaft 2 through the cross secti on g to lo, "the to frame i suitable manner. Keyed to armature shaft 6 is collar 11 carrying sirens 12. To said coiisr' 11 is one fastened end of spiral sgiring 13, said spiral sggring g spark of sufiicient in-" of the spark so as to,

encircling armature shaft 6 and comlectiu at its outer end to gear 5. said gear hmi pins extending therefrom adapted to em arms 12 as shown at 14, said gear having pins 15 projecting therefrom in positions shown and for the purpose hr after described. Projecting from ge are pins 16 in their proper relative posi to pins 15 on gear In frame i toned stud 17. On the inner end of san stud and movable thereon is detent 1R. ing arms 19, 20, and 21, bent and torn shown in thedrawings, said detent l held steady in position by friction u 22, and prevented. from rotating too stop pins 23. Against the inner ed gear 4 and resting on hearing 3 is a block 2%. Said block 24 is moved bar. forth by helical cam 25, the operated by lever 26 and shaft i, or i in place by catch 27 and notched The operation of my invention is loivs:-liever 26 has two positi normal position block 24. is in shown in the drawing. "nos saio 26 is thrown into the second position.

is keyed gear 4, the some meshing with gear.

cal cam 25 throws block tori-raid. advancing gear 4 with its pivots 16. earn shaft 2. Said pins 15 thereupon nately come in contact with arm 1.9 tent 18. When one pin 16 strikes sai 19, arm 20 of said detent is thrown to and stops arm 12 of collar 11. and as quently stops the revolution of HliTlEi. shaft 6. As gear 5 continues to revolv armature shaft 6, spring 13 is Wound At a predetermined period in the revolnti of gear 5. pin 15 strikes arm :21 on throws arm 20 cit of arm spring 13 causes said arm 12 to ward to its original position pins 14-. Since arm 12 is a 11, which is keyed to Zlllnuolli armature shaft 6 is thus roads to him Ward so quickly as to produce a sutlicicnt intensity to fire the in starting when the engine slowly by hand or others ll hile Figs. 1, 3, and ferred embodiment of my show in Figs. 4 5, and ed: bodiment of my invention neto is connected direct without gears; the seine being used as are used In this embodiment, the
